A laboratory experiment was conducted to determine the effect of salinity stress (0 dSm-1, dSm-1, 6 dSm-1 and 9 dSm-1) on germination and seedling growth of 100 germplasm lines of sorghum (Sorghum biocolor), collected from different agroclimate zones of Rajasthan. The analysis of variance for all the traits revealed considerable variability in the experimental material and environments. In present study, the trend of genotypic and phenotypic correlation was similar between different characters. Three genotypes, viz., Raj 27, Raj 30 and Raj 4 could be identified for salinity tolerance as they were stable and having bi>I and high germination percentage at the highest (9 dSm-1) salinity level. Another genotype Raj 42 though was not stable but it exhibited higher mean performance in all salinity levels for fresh weight of root per seedlings, coleoptile length, germination percentage and ratio of fresh weight of shoots to roots
